does anyone have any idea why my iowait suddenly tripled after the machine rebooted with the new kernel?

this system is single node running on a single 1tb nvme m.2 drive with lvm-thin.
iowait was always averaging around 2%, but suddenly its 6.x% without any visible reason.
i would like some advice on this.
